一个data file "size“
含有数值：72 95
data a;
infile "size" ;
input@ 1 height 2. @4 weight 2;
run;
viewtable 里是
height weight
72 2

weight 为什么是2 ？

因为你 input@ 1 height 2. @4 weight 2；写错了
2后面忘记写. 了

Let's focus on the code, "input @1 height 2. @4 weight 2;", in which the number 2 after 'weight' means thet SAS would read and put the second character into 'weight' only.

And furthermore, if we write in this way, "input @1 height 2. @4 weight 1;", the value of 'weight' in dataset 'a' would be 7.
